The GTR drive train is not without it's quirks.
The front diff is located in the GTR sump, and is pretty much impossible to adapt to something else (I have attempted this myself) and the available diff gear ratios are limited.
The front prop shaft is also on the same side as you, and the...
A great achievement Donald.
With a lot of this stuff, raw engineering can only take you so far, the final bit is about tuning, tweaking, and optimization.
Thanks Greg.
There are probably several potential causes of torque steer, and as you say, more torque and tractive effort multiplies whatever is going on.
Tex, the lower lateral link is not as heavily loaded during braking and acceleration as it is in cornering.
It is the radius link that suffers most of the pushing and pulling, during braking and acceleration.
I know it is not really all that clear cut and simple, but you can probably see what I...
As you know the 323/Laser uses a typical strut type front suspension.
While high lateral cornering forces will certainly create some definite compliance steer, pure tractive effort should not.
The front wheels may move forwards slightly due to rubber compliance, but there is nothing there to...
If small torque change does not show up on a current meter, it will not show up on a watt meter either.
The internal inertia of the fast spinning drive motor, and friction in the transmission, will mask small cyclic torque fluctuation in the output shaft. The motor current will be very...
Yes, but the original poster referred specifically to "modern" turbos, which to me implies ball bearings.
Those don't have a single dedicated thrust bearing, but use the angular contact ball races at each end of the housing to locate the shaft.
Shaft expansion will tend to close up any end...
You can buy rotary torque transducers.
The basic idea is usually some type of torsion bar with rotary encoders at each end.
As more torque is applied, one end lags the other, and you get a variable duty cycle digital output proportional to torque.
Axial tolerance can never be zero, because there absolutely must be allowance for thermal expansion.
As Dick says, the type and size of turbo will change things greatly.
Anecdotal evidence is all you are likely to get on an internet Forum.
Best to contact the manufacturer of the specific...
A belt is probably the best way to go.
Check out these Vortron high pressure air blowers. These run at those sort of speeds and power levels. You might even be able to buy some Vortron spare parts to do your job....

It is not normally very easy to do a back to back test on the same car with similar versus different front driveshaft lengths !
But I have had the opportunity to do exactly that.
In Australia the Mazda 323/ Ford Laser comes normally aspirated with unequal driveshafts, turbo with a different...
Not that I am aware of.
The problem is this type of testing is fairly obscure, and so the test equipment needs to be custom made to suit the specific application.
A lot of this type of analysis is done these days by computer simulation, often using "Spice".
But that can only take you so far...
